Hey guys, so I was reading through different threads, but no one seemed to talk about a couple things:

1st picture: The Awd sump doubles as mounting points for the transmission.  If you use a RWD sump, you lose those bottom 4 mounting points as there is no way to mount the two (r33 rwd) brackets to the NEO block (picture 2) like on the series 2 r33 rb25 (picture 3 shows the bracket mount points on r33 block).  For those that have converted awd to rwd - are you just not using those 4 bottom trans mount points?  Obviously, you could cut and weld the AWD sump and call it a day, but my preference is to not hack anything.

4th picture:  pilot bushing for r33 rwd trans shown next to where it should go on the Neo motor, but clearly has a different size pilot bushing for auto.  I see people are talking about pulling this auto bushing out, but then what? The manual bushing is too small to fit 🤔

All people seem to talk about is whether or not a RWD sump will fit an AWD block 😁

Thats an ENR33 GT4  RB25de block. Part No.1100023U00   There should be 23U cast into block. IT IS NOT a neo block they are 6L1 blocks

You need a 1100075T00 block they have 75T cast into the block. The correct pilot bush is part no.32202B950A

Its got the 23U stamp.

It was sold as a Stagea engine, but the ECU 23740-cr700 cross references to a Cedric/Gloria. The turbo also had a metal compressor wheel fwiw, which definitely came stock on this motor as nothing seemed to have ever been worked on.

Anyhow, Im assuming the 75T block has the mount points I need.  If im not mistaken - my series 2 rb25det motor is the 75T block.

I guess its time to hack up the AWD oil pan..

I didn't use the bottom mounts and went with an ASR sump. The pickup was modified to suit the ASR sump as well.

Totally binned the spigot as it's not needed.

Bad photo, but this is how it looks atm mounted to a RWD R33.

Yes, absolutely correct Bret, the 75T was used in R33series 1&2 and R34 Neo RWD RB25 Skylines both turbo and N/A.

Johnny you are saying you use no spigot at all?

Hmmm... come to think of it, I believe I put in a manual one and binned the auto one.
